BALL-BEARING FOR SHAFTS.

SPECIFICATION forming part of Letters Patent No. 331,898, dated December 8,1885.

Application filed November 6, 1885. Serial No. 182.064.

T all whom, it ntay concern.-

Be it known that I, JOHN M. MARLIN, of New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Ball-Bearings for Shafts, of which the following is a specification.

My improvement relates to ball-bearings for shafts; and it consists in certain novel combinations of the several parts thereof to facilitate their use and adjustment, substantially as hereinafter described and claimed.

In the drawings, Figure 1 is a side view of one of my ball-bearings complete. Fig. 2 is a transverse section of the same upon the shaft. Fig. 3 isaside view of the outer clamping-ring. Fig. 4 is an edge view of the same. Fig. 5 is a side view of the outer hall-bearing ring. Fig. 6 is a section of the same on line a: a of Fig. 5. Fig. 7 is a side view of the removable portion of the ring. Fig. Sis an end view of the same. Fig. 9 is a side view of the outer covering-ring. Fig. 10 is an end view of the same.

S is the shaft, which is to revolve within the ball-bearing. A is the outer clampingring, provided with a hole, a, through an ear upon one side of it, to allow the bearing to be bolted to the part of the frame of the machine which sustains the bearing. This outer ring is split upon one side, and has two ears, a a, on each side of the split portion, with a hole transversely through them, in which a screw-bolt, a is screwed. The point end of the bolt enters a thread in the corresponding ear in the usual manner, and closes the cars a a togetherto clamp the outer ball-bearing ring more or less upon the balls. Within the ring A is placed the outer ball-hearing ring, B. This ring has a V-shaped groove cut around its internal periphery to inclose the halls, and a section, 1), corresponding in shape to the ring, fits into a slot, b, in one side of the ring, which is cut in it wide enough to receive one of the balls through it. The purpose of this slot is to allow the balls to be readily removed and replaced without removing the hearing from the shaft, and in order to facilitate adjustment of the ring B upon the halls the section bis made somewhat (No model.)

shorter than the slot 1), into which it fits, as shown in dotted lines in Fig. 1.

After the outer ball-bearing ring, B, is slipped within the clamping-ring A two side covering-rings, C C, are placed against the faces of the rings A B and the segment b, andjsccured in place by screws 0 c, threaded into holes 0' c in ring B, passing through holes 0 c in the covering'rings C, thus excluding all dust and dirt from the bearing, and holding the section or segment I) in line with the ring.

In order to allow of the adjustment of the ball-bearing by screwing or unscrewing the screw a without removing any of the parts, the holes 0 through the face-covering rings are made larger than the shanks of the screws 0, which pass through them, as shown in dotted lines in Fig. 1, and by slightly loosening these screws the turning of the screw a compresses the outer clamping-ring, A, more or less upon the outer hall-bearing ring, B, and closes the latter more or less upon the balls, when the screws 0 may be tightened, and the facecovering rings C drawn closely against the other parts of the hearing, as shown.

A groove, 8, is made in an enlargement upon the shaft, for the purpose of receiving the balls, as shown in Fig. 2.

In order to adj ust this bearing upon the shaft, I first slip the ring B over the groove 8, and introduce the balls through the slot 1) into the groove 8 and the surrounding groove of the ring B until they are filled, the last ball being in the lower side of the slot 5. I then insert the segment bin place in its slot. I then slip over the ring B and segment I) the outer clamping-ring, A. I next screw on each face the covering-ring C without turning up its screws 0 quite tight. I then screw up the screw a closing the rings A and B over the balls until they are properly adjusted, when, by screwing home the screws 0, the operation is completed.

WVhat I claim as new and of my invention is- 1. In combination with the shaft S and the balls, the outer ball-bearing ring, B, provided with a slot, Z2, the segment I), made shorter than said slot, and the outer clamping-ring, A, substantially as described.

2. In combination with the shaft S and the balls, the outer ba11-bearing ring, B, provided with a slot, b, the segment I), made shorter than said slot the outer clamping-ring, A, and the 5 face-covering rings 0 0, having their holes 0 0 larger than the shanks of the screws 0 0, substantially as described.

3. In combination with the shaft S and the balls, the outer ball-bearing ring, B, provided with a slot, b, the segment I), made shorter than IL said slot, the outer clamping-ring, A, and the outer side covering-rings, O O, overlapping the opposite faces of the rings B and A, substantially as described.
